PUMPING-JACK FOR OIL-WELL PUMPS.

SPECIFICATION forming part of Letters Patent No. 586,502, dated July 13,1897.

Application filed January 14, 1897. Serial No. 619,242. (No model.)

.To all whom it may concern.-

Be it known that 1, THOMAS G. LANEY, a citizen of the United States,residing at Lima, in the county of Allen and State of Ohio, haveinvented new and useful Improvements in Pumping-Jacks for Oil-TellPumps, of which the following is a specification.

This invention relates to that class of pumping-jacks for oil and otherwells wherein a p ivoted bell-crank lever is connected at one end withthe polish or pump rod and at the other end with an engine or motor forthe purpose of working the pumping mechanism.

The chief objects of myinvention, concisely stated, are to provide asolid and strong base or support for the pumping-lever of the jack, toprovide novel means rfor connecting the pumping-lever with thepolish-rod whereby thelatter will be reciprocated in a perpendicularplane with no liability of being bent or forced laterally Vout ofplumbdne, and to provide new and improved devices whereby a polish-rodreciproeated by the pivoted lever of a pumping-jack can be axiallyrotated to loosen or remove paraffin while it is firmly and securelyheld in operative connection with the pumping-lever on the downstroke ofthe pump.

To accomplish lthese objects my invention involves the features ofconstruction, the combination or arrangement of parts, and theprinciples of operation hereinafter described and claimed, referencebeing made to the accompanying drawings, in which-` Figure 1 is a sideelevation of my improved pumping-jack in operative connection with thepolish-rod of an oil-well pump. Fig. is a sectional side elevationlooking in the direction of the arrow, Fig. 1. Fig. 3 is a detailelevation of the pumping-lever and its base or support. Fig. 4 is adetail view showing the device by which the pull-rods are connected withthe pumping-lever. Fig. 5 is a detail sectional plan view taken on theline Fig. 6 is a detail plan view of the cross-head, to which thepolish-rod is connected by a clamp; and Fig. 7 is a detail plan view ofthe sectional clamp for connecting the tubing with the base or supportof the pumping-lever through the medium of tie-bolts.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, wherein- Thevnumeral 1 indicates the head of the well-casing,from which rises to a suitable height the tubing 2, having near itsupper end a stuffing-box 3 and a lateral outlet 4, designed to connectwith an oil-tank. The polish-rod 5 of the pumping mechanism extendsthrough the stuffing-box and is rigidly clamped at its upper portionbetween two clamp-sections 6 and 7, united through the medium of bolts 8and constructed on their inner sides with semicircular grooves toreceive a circular enlarged head 9, rising from the center of across-head 10, the construction being such that the clamp can turn onthe cross-head, and, as the clamp grips the polishrod, the latter can beaxially rotated 'in the cross-head for the purpose of loosening orremoving paraffin.

The ends of the cross-head 10 are rigidly connected with a ring orcollar 12 through the medium of verticaltubes 13 and tie-bolts 14,whichpass through the tubes and are suitably connected Lo the cross-head andto the ring or collar. As shown, the lower ends of the tie-bolts 14 arescrewed directly into the collar or ring, while their upper ends aresecured to the cross-head by screw-nuts 15. The collar or ring 12 issusceptible of sliding vertically upon the tubing 2 and is preferablyeonstruoted with a sleeve-like portion 16,which materially aids inguiding the collar or ring in its reciprocating motions on the tube. Thering or collar is connected by rigid rods 17 with one arm of abell-crank lever 18, pivoted at its angle, as will hereinafter appear,and comprising two arms 19 and 20, which in the normal position of thelever project, respectively, vertically and horizontally. The horizontalarm 2O is bifurc'ated or forked to provide two opposite members 21,having vertical sockets 22 formed therein; These sockets are preferablyoblong in cross-section to permit the necessary motions of the rigidrods 17, as will hereinafter appear. The upper ends of the rods 17 arepivotally connected with the ring or collar 12 through the medium oftransverse pivot-pins 23, and the lower en ds of the rods are connectedwith pins IOO 24,which project through segmental slots 25, formedlaterally through the members 21, all in such manner that while thebell-crank leV ver moves in the arc of a circle the rigid rods 17 willpractically operate to move the ring or collar 12 in a perpendicularplane upon t-he tubing 2, and through the rigid connections ofV thisring or collar with the cross-head 10 the polish-rod willbe positivelyreciprocated in I a right line with no danger or liability of beingbent, forced, or moved laterally out of perpendicularity.

The bifurcated or forked construction ofV /tween which the ends of thepintle portion 25 of the lever t and by which the lever is held againstdisplacement. A bolt 28 passes through the pintle portion 25fl of thelever and through the ears or lugs 27 for the purpose of holding thelever in operative connection with the casting. This casting constitutesa solid and strong base or support for the lever, and at its bottomportion it is constructed with a base-plate 2), designed to rest upon atimber foundation, as at 30. The base portion of the casting isconstructed withtwo opposite parallel bolt-holes 3l, through whichtie-bolts 32 extend. The tie-bolts are secured at one end to the castingby screw-nuts 33, and at their other ends they are connected with aclamp-ring composed of two sections Si, rigidly clamped upon the tubing2 by screwnuts 35, applied to the tie-bolts 32. The tie-bolts serve torigidly connect the casting 2G with the tubing 2, and by this means thecasting is firmly braced and held during the rocking motion of thepumping-lever in operating the polish-rod.

The vertical arm 19 of the pumping-lever is connected by pull-rods 36with an engine or motor (not shown) for the purpose of rocking thelever. The ends of the pull-rod encircle a sleeve 37, arranged in anyone of a series of circular holes 3S, provided in the vertical arm ofthe lever. The series of holes SS render it possible to adjust theconnection of the pull-rods with the lever for the purpose of varyingthe strokes of the latter and enabling it to make longer or shorterstrokes to suit the conditions required. The sleeve 37 is form ed at oneend with an enlarged head 39 and is provided at the other end with adetachable enlarged head 40, held in place by a bolt 41 passing throughthe sleeve. By this construction it is possible to fit the sleevethrough eyes formed in the ends of the pullrods and then to apply thehead 40 and bolt 41, so that the pull-rods are securely connected withthe lever through the medium of a pivthe upper ends of the rods and thepin-andslot connection of the lower ends of the rods with thepumping-lever.

The interlocking connection between the clamp-sections G and and thecross-head 10 effectually prevents the disengagement of the clamp fromthe cross-head on the downstroke of the polish-rod. Inasmuch as the head9 of the cross-head is circular and fits circularly-shaped grooves inthe clamp-sections 6 and 7 and rigidly clamps the polish-rod it ispossible to axially rotate the latter by simply rotating theclamp-sections by any suitable means. I do not, however, confine myselfto rotating the polish-rod by acting upon the clamp-sections, as it ispossible to rotate the polish-rod by rst loosening the nuts of the boltsS, so that'the polish-rod can be turned independent of theclamp-sections.

The semicircular pintlesocket in which the pintle portion 25 of thepumping-lever seats is adapted to contain a supply of lubricatingmaterial, and the same remarks apply to the vertical sockets 22 in thebifurcated or forked end of the lever.
